[Remove row from array and move next value into place etc]

Hmm, thanks, getting close, but I don't think that'd work. If I had two arrays, and wanted to cut out part of the first one or add the second to it, it'd work.

 

I might just have to go with a for loop... gosh, I'm surprised.

[Remove row from array and move next value into place etc]

If you think there is no such function and I should just use a for loop to iteratively set the keys back one number after the one I delete, please tell me. I need to work on this today. I just want to save processing power and time if I can.

[Rand of 5 options using % chance]

Yeah.

 

Create a random number up to a maximum, say 100.

 

If < 25 then you have a 25% chance of doing a

If > 50 then you have a 50% chance of doing b

If > 25 then you have a 75% chance of doing c

 

You see what I'm getting at. Change the numbers and get your brain in a mathematical mood and find the correct numbers for what you want to do. The max random number and the individual numbers will vary depending on how many choices you want and the intended %'s but that is the basic solution.

[Remove row from array and move next value into place etc]

Hi,

 

Let's say I have an array like this:

 

$array[0] = "ball";

$array[1] = "bat";

$array[2] = "glove";

$array[3] = "referee";

$array[4] = "strike";

$array[5] = "home run";

 

Now, let's say I want to get rid of [3] but move the next values up, automatically, into 3,4.

 

For example,

 

$array[0] = "ball";

$array[1] = "bat";

$array[2] = "glove";

$array[3] = "strike";

$array[4] = "home run";

 

Is there a way to simply do this? I could do it using for loops, but is there a simpler way, like a built in function, that will do this for me?

 

Thanks,

 

Matthew

 

 

[Searching the yellow pages...]

Hmm, yes very interesting.

 

Does anyone know a resource that I could use, I'd love to have something like

 

$addresses = file('http://site.com?find=mysearch&where=60477');

 

and have it return matching addresses...

 

[Searching the yellow pages...]

What I would love to have is addresses within a certain zip code based on what I search put into an array.

 

For example, I put in "police station" and this hypothetical PHP program goes and searches google, or mapquest/yahoo etc, and returns a neat array of information that I can use to create points on a google map.

 

Does this exist? Is there any way to use PHP to run and return an address search on an external site like google or mapquest?

[Creating Registration Keys]

I would like to create license/registration keys for my online application. I have never done this before so I do not know where to start.

 

I suppose I would like a randomly generated string that could be compared to a static value and then a TRUE or FALSE could be returned. I do not know how to do this though. Of course, it gets tricky because I'd need more than just a 1:1 correspondence (like if I used md5()). I'd need several different strings (thousands even) adding up to the same value somehow.

 

How is this possible? How does Microsoft and all the other non-free software vendors create their CD keys and make sure they are valid?

 

Thanks!

[Figuring out the beginning of the week with timestamps]

How do I figure out when the current week starts with timestamps? I figured it out with months, for example:

 

$thisMonth = date(d) * 24 * 60 * 60;

$thisMonth = time() - $thisMonth;

$thisMonth = date(Ymd,$thisMonth);

 

This would give you a timestamp pertaining to the beginning of the month. I want to get one pertaining to the beginning of the week, which seems more complicated. For example, today falls in the second week of feburary. The beginning of the week was the 5th. I need to find some way to figure out on which date the first day of the given week falls.

 

Thanks,

[SQL Code Stripping... preventing SQL injections?]

Does anyone know if there is a way to strip out SQL code from $_POST variables?

Perhaps a function similar to strip_tags but instead of catching HTML, it catches SQL statements?

Thanks,

[Upload Script]

You need to post the error otherwise people will not know what to look for in your script.

[Count function won't return 0 when counting arrays from the DB]

Thank you very much- I used the following code:

if ($family_accounts != FALSE) {
        $count = count($family_accounts);
}
else {
        $count = 0;
}

[Count function won't return 0 when counting arrays from the DB]

$result... (yadda yadda, postgresql query);
$row = pg_fetch_all($result);
$count = count($row);

The strange thing is, $count is never = 0 when there is nothing to be found. It always returns at least a value of 1. Why is this happening?

Thanks,

Matt

[File uploading taking up large amounts of memory]

Yes, but if I set the memory to 50M, wouldn't it crash my server (or at least bring it to its knees) if more than a few people were using it at the same time?

But in any case, it's not normal for a 512kb file to hog up over 12 megs of ram right?

[Upload problem!]

You've gotta cut and paste the error message it's given you so we can compare it to the code, otherwise it doesn't help us.

[PHP Final Year Degree Project help??]

did you make sure the module is set to load in apache's config file? (httpd.conf?)

Look for "loadmodule mysql"...(something) in httpd.conf

If it is "commented out", meaning it looks like:

;loadmodule mysql...

Then remove the semicolon, then restart apache.

[File uploading taking up large amounts of memory]

For some reason, uploads are taking up much more memory than the actual file size. For example, I tried to upload a 640K jpg and I set a memory limit per script of 12MB, and that file made the script go over the limit and it crashed. ???

Why are file uploads of 640KB making my script use up more than the 12 meg limit and crash? Is there any way to fix this, short of restricting the file size people can upload?
